Still making progress, still wish I had the perfect grey in my stash but moving on without it!
I have the two yellow triangles on each of the blocks, today is putting on the black triangles. I've been able to slide around my ruler a bit to avoid having any of the Black triangles turn into yellow, since I had a couple spare inches per strip that's working fine, getting the same 4 squares/8 triangles as I did from the yellow where I didn't have to think, care of worry a bit.
Picture 1 shows the four sets of completed 10" inner blocks. Picture 2 shows the lone finished block, I think it is 14" finished?? Easy enough to measure even if it hasn't set in my brain yet.
